The influence of investment experience on market prices: laboratory evidence

We run laboratory experiments to analyze the impact of prior investment experience on price efficiency in asset markets. Before subjects enter the asset market they gain either no, positive, or negative investment experience in an investment game. To get a comprehensive picture about the role of experience we implement two asset market designs. One is prone to inefficient pricing, exhibiting bubble and crash patterns, while the other exhibits efficient pricing. We find that (i) both, positive and negative, experience gained in the investment game lead to efficient pricing in both market settings. Further, we show that (ii) the experience effect dominates potential effects triggered by positive and negative sentiment generated by the investment game. We conjecture that experiencing changing price paths in the investment game can create a higher sensibility on changing fundamentals (through higher salience) among subjects in the subsequently run asset market.     

A solution to the hold-up problem involving gradual investment

We consider a setting in which the buyer's ability to hold up a seller's investment is so severe that there is no investment in equilibrium of the static game typically analyzed. We show that there exists an equilibrium of a related dynamic game generating positive investment. The seller makes a sequence of gradually smaller investments, each repaid by the buyer under the threat of losing further seller investment. As modeled frictions converge to zero, the equilibrium outcome converges to the first best. We draw connections between our work and the growing literature on gradualism in public good contribution games and bargaining games.     

基于公平心理偏好的投资博弈——敲竹杠问题的一个行为解决

敲竹杠问题是不完全合约理论的中心话题,经典文献认为,如果合约是不完全的,当事人的专用性投资会引发敲竹杠风险从而导致无效率的专用性投资。但是,关于敲竹杠问题的文献通常假定事后谈判结果对事前投资成本不敏感。通过在雇佣双方的投资博弈中引入投资成本相关性这种合作的谈判方式,将传统敲竹杠模型中影响谈判力的因素与当事人对公平偏好的行为因素二者融合,本文证明:与传统的投资博弈相比,在投资成本影响企业(雇员)谈判力的情况下,双方有更强的专用性人力资本投资激励。雇佣双方所面临的敲竹杠风险取决于双方的初始谈判力,且双方有可能在事前做出社会最优甚至过度的投资。这也从一个方面解释了现实中大量存在的有效投资现象。     

基于期权博弈理论的资源类景区投资决策框架的构建

越来越多的企业参与到资源类景区的投资中。该类景区投资的不确定性、不可逆性和竞争性,使得传统投资决策方法和理论存在很大的局限性。为此必须在景区投资决策中引入新的投资决策方法和理论。实物期权方法解决了项目未来收益的不确定性、投资成本的沉没性和项目执行的灵活性,博弈理论解决了实物期权的共享性和竞争对手的反映。因此要在资源类景区投资决策中,构建基于期权博弈理论的投资决策构架。     

Bounding preference parameters under different assumptions about beliefs: a partial identification approach

We show how bounds around preferences parameters can be estimated under various levels of assumptions concerning the beliefs of senders in the investment game. We contrast these bounds with point estimates of the preference parameters obtained using non-incentivized subjective belief data. Our point estimates suggest that expected responses and social preferences both play a significant role in determining investment in the game. Moreover, these point estimates fall within our most reasonable bounds. This suggests that credible inferences can be obtained using non-incentivized beliefs.     

Coordinating development: Can income-based incentive schemes eliminate Pareto inferior equilibria?

Individuals' inability to coordinate investment may significantly constrain economic development. In this paper we study a simple investment game characterized by multiple equilibria and ask whether an income-based incentive scheme can uniquely implement the high-investment outcome. A general property of this game is the presence of a crossover-investment point at which an individual's incomes from investment and non-investment are equal. We show that arbitrarily small errors in the government's knowledge of this crossover point can prevent unique implementation of the high-investment outcome. We conclude that informational requirements are likely to severely limit a government's ability to use income-based incentive schemes as a coordination device.     

Would Excess Capacity in Public Firms Be Socially Optimal?

We analyse oligopolistic interactions between a welfare-maximizing public firm and a profit-maximizing private firm in a repeated game. We find that the public firm can hold excess capacity as a strategic punishment device to sustain a subgame perfect equilibrium which is welfare-superior to the static Nash equilibrium. Basically, potential punishment from the public firm in the dynamic game can make the self-interested private firm behave in the public interest. Furthermore, if capacity is endogenous, public excess capacity can occur in a welfare efficient equilibrium when the cost of public capacity investment is higher than that of private investment.     

外资质量与引资优惠政策分析——基于博弈论的分析框架

从东道国与外商投资者的博弈行为出发,构建了一个用于分析外资优惠政策调整的动态博弈模型,据此模型得到三个命题:东道国引资过程满足边际收益等于边际成本条件,优惠政策的边界条件取决于收益系数、成本系数以及最佳外资规模的大小;优惠政策与投资环境具有反向的替代关系,与外资的最佳规模呈正比关系;低质量的投资对环境的敏感系数要小于高质量投资,低质量的投资对优惠政策的敏感系数要大于高质量投资。并用这三个命题对中国外资政策调整的历程做了解释。

Rational exuberance

We study a two-player investment game with information externalities. Necessary and sufficient conditions for a unique symmetric switching equilibrium are provided. When public news indicates that the investment opportunity is very profitable, too many types are investing early and investments should therefore be taxed. Conversely, any positive investment tax is suboptimally high if the public information is sufficiently unfavorable.     

Investment decisions and coordination problems in a market with network externalities: An experimental study

We study decision-making and the associated coordination problems in an experimental setting with network externalities. Subjects decide simultaneously in every round how much to invest out of a fixed endowment; the gain from an investment increases with total investment, so that an investment is profitable iff total investment exceeds a critical mass. The game has multiple, Pareto-ranked equilibria; we find that whether first-round total investment reaches critical mass predicts convergence towards the Pareto optimal full-investment equilibrium. Moreover, first-round investments and equilibrium convergence vary with critical mass and group size in a complex way that is explicable by subtle effects of strategic uncertainty on decision making.     

Investment dynamics with common and private values

We study a dynamic investment game with two-dimensional signals, where each firm observes its continuously distributed idiosyncratic cost of investment and a discrete signal correlated with common investment returns. We demonstrate that the one-step property holds and provide an equilibrium existence/characterization result. “Reversals” are possible, where a large number of firms investing in a given round becomes bad news about investment returns. Welfare is compared to static and rigid-timing benchmarks, and computed for large economies.

两税合并对引进外资的影响及对策分析

"两税"并存,让外资企业享受"超国民待遇",吸引外商投资,作为特定历史条件下的权宜之计,无可厚非。但随着经济的发展、时代的变迁,更需要有一个公平、公正的市场竞争与投资环境。基于自身的利益,围绕新税制的设计,各方曾有过激烈的博弈。本文就博弈的解数之一,即统一税制后是否会对引进外资产生严重的影响及如何应对问题,发表个人的浅见。     

Coordination cycles

Players repeatedly face a coordination problem in a dynamic global game. By choosing a risky action (invest) instead of waiting, players risk instantaneous losses as well as a loss of payoffs from future stages, in which they cannot participate if they go bankrupt. Thus, the total strategic risk associated with investment in a particular stage depends on the expected continuation payoff. High continuation payoff makes investment today more risky and therefore harder to coordinate on, which decreases today's payoff. Thus, expectation of successful coordination tomorrow undermines successful coordination today, which leads to fluctuations of equilibrium behavior even if the underlying economic fundamentals happen to be the same across the rounds. The dynamic game inherits the equilibrium uniqueness of the underlying static global game.     

扶持我国出口导向企业实施RRC战略的理论依据

文章探讨本国企业与外国企业在以产量竞争的方式争夺出口市场的情况下,本国政府对本国企业实施提高竞争对手成本(RRC)战略的投资进行补贴的理论依据。通过两次运用两阶段博弈,文章对由补贴政策、企业RRC投资、产量和利润水平决定构成的三阶段博弈进行了因果关系的比较静态分析,认为在一般情况下,对本国企业RRC投资补贴有利于本国企业在国际市场中产量、市场份额和利润的增加,也有利于本国社会总福利水平的增加,对外国企业产量、利润和社会福利则形成负面影响。由于RRC战略较之掠夺性定价温和且更易实施,这一政策对于保持我国出口稳定增长具有一定积极意义。     

On the Relation Between Asset Ownership and Specific Investments

Experimental results are presented for a simplified version of Hart's (1995) theory of the firm. Theory predicts that investment levels remain constant when investors' no-trade pay-offs increase, if these pay-offs are threat points. While they may decrease when no-trade pay-offs are outside options. Our results support these predictions in a relative sense. Average investment levels exceed the predicted level. Actual investment behaviour is consistent with the outcomes of the bargaining stage. The play of the game is supported by a reciprocity mechanism in which non-investors consider higher investment levels as fair behaviour which deserves a reward. Investors anticipate this.     

Options in technology investment games: The real world TFT-LCD industry case

The Thin Film Transistor-Liquid Crystal Display (TFT-LCD) industry has demonstrated that the investment of huge amounts of capital in new plants is a key factor for success. Decisions about investing in the latest generation of plant involve billions of dollars and a great deal of uncertainty. Moreover, the industry shows distinct oligopolistic characteristics, so the first mover's reactions must be considered when making capital decisions in such competitive environments. The traditional net present value (NPV) rule is a ‘now-or-never’ concept that fails to capture the need for managerial flexibility, which is especially important when investments are irreversible and involve a great deal of uncertainty. In this paper, we use a combination of real options and game theory to analyze the investment strategies of a case company in the TFT-LCD industry. The results show that real options reveal the value of flexibility, which NPV fails to consider. In addition, we apply game theory analysis to different investment strategies to demonstrate the decision-making processes used by competing companies.

Market Games in Large Economies with a Finite Number of Types

We study market games derived from an exchange economy with a continuum of agents, each having one of finitely many possible types. The type of agent determines his initial endowment and utility function. It is shown that, unlike the well-known Shapley–Shubik theorem on market games (Shapley and Shubik in J Econ Theory 1:9–25, 1969), there might be a (fuzzy) game in which each of its sub-games has a non-empty core and, nevertheless, it is not a market game. It turns out that, in order to be a market game, a game needs also to be homogeneous. We also study investment games – which are fuzzy games obtained from an economy with a finite number of agents cooperating in one or more joint projects. It is argued that the usual definition of the core is inappropriate for such a model. We therefore introduce and analyze the new notion of comprehensive core. This solution concept seems to be more suitable for such a scenario. We finally refer to the notion of feasibility of an allocation in games with a large number of players. Some of the results in this paper appear in a previous draft distributed by the name “Cooperative investment games or Population games”.
